  • The State Playbook for Equitable Data-Center Growth
    2025/10/28

    AI’s explosive growth is reshaping America’s electric grid. In this AIxEnergy conversation, host Michael Vincent and energy economist Brandon Owens explore how state policies can ensure fairness as data centers drive massive power demand. Owens explains that while tech giants like Amazon and Microsoft insulate themselves through private energy deals, households face rising bills. Using examples from Maryland, Texas, and Georgia, he argues that policy—not technology—determines who pays. States can adopt large-load impact fees, congestion-cost allocation, and flexible-load tariffs to make AI growth equitable, while investing in community benefits and shared infrastructure. The takeaway: smart governance can turn the AI power surge from a social burden into a public good.

  • The Carbon Cost of Intelligence: Will Hyperscalers Accelerate Decarbonization—or Default to Fossil Fuels?
    2025/10/01

    Artificial intelligence has unleashed the fastest-growing source of new electricity demand in U.S. history. Unlike past industrial loads that spread gradually across regions, AI demand clusters in hyperscale data centers—each consuming hundreds of megawatts, with campuses now reaching the gigawatt scale. Four companies—Amazon, Microsoft, Google, and Meta—control most of this build-out, giving them extraordinary influence over the nation’s power system. Their choices on siting, procurement, and infrastructure will determine whether AI accelerates the clean-energy transition or locks in fossil dependence.

    These hyperscalers are now “quasi-utilities.” Their decisions steer utility resource plans, transmission, and wholesale markets. They are underwriting gigawatts of wind, solar, and nuclear, yet their growth risks overwhelming grids still dependent on natural gas for firm supply.

    Company strategies diverge:

    • Amazon is the world’s largest renewable buyer, but its heavy concentration in Virginia risks driving new gas plants even as it invests in a nuclear-adjacent Pennsylvania campus. It relies on annual renewable accounting, leaving gaps during fossil-heavy hours.
    • Google pioneered 24/7 hourly carbon-free accounting, discloses campus-level results, and shifts workloads to renewable-rich regions. Yet without firm clean supply, its model defaults to gas when renewables sag.
    • Microsoft is the most diversified, blending solar, wind, nuclear contracts, hydrogen pilots, and even fusion bets. It is also testing hydrogen fuel cells to displace diesel backup. But it remains tethered to fossil-heavy utility portfolios.
    • Meta is the least sovereign, relying heavily on colocation providers. While it has invested in renewables, it has also explored gas generation, making it the most exposed to fossil dependence.

    The report identifies five partnership archetypes shaping outcomes:

    • Tenant–host reliance, where companies inherit the host’s mix (Meta).
    • Hardware–software intensity, where load growth outpaces clean supply.
    • Energy and infrastructure supply, combining contracts with asset control (Amazon, Google, Microsoft).
    • Developer–hyperscaler dependence, where customers inherit sustainability downstream.
    • Deployment at the edge, which risks “dirty redundancy” if powered by diesel or gas.

    Velocity is the critical bottleneck: data centers rise in two years, while transmission and interconnection take a decade. Renewable projects are already queued into the 2030s, leaving natural gas as the default backstop. Unless hyperscalers recalibrate, their growth may compel utilities to build new gas capacity at the very moment fossil use should be declining.

    The report outlines four pivots to avoid this outcome:

    • From procurement scale to systemic alignment—co-finance transmission and interconnection, not just buy generation.
    • From accounting to firm zero-carbon capacity—contract for nuclear, geothermal, long-duration storage, and hydrogen.
    • From rigid to flexible demand—align non-critical workloads with renewable availability.
    • From speed to sovereignty in colocation—mandate clean procurement standards or co-invest in local clean supply.

    These shifts are within reach. Amazon’s purchasing power, Google’s accounting leadership, Microsoft’s experimental drive, and Meta’s scale all offer leverage to move from “100 percent renewable” marketing to genuine zero-carbon reliability.

    The paradox is stark: the same firms most likely to entrench natural gas are also best positioned to break its dominance. If they succeed, hyperscalers could decarbonize the grid faster than any government mandate. If they fail, AI will rise on a brittle scaffold of gas turbines.

  • The Grid Divide: Which States Will Power the AI Economy—and Which Will Be Left Behind
    2025/09/18

    Artificial intelligence is triggering an electricity demand surge unlike anything the U.S. grid has faced in decades. By 2028, data centers will consume two to three times more power, and by 2030 nearly half of all new U.S. electricity demand could come from AI. The AI revolution is no longer about code or GPUs—it is about gigawatts.

    Yet the growth is not evenly distributed. A handful of states are sprinting ahead, positioning themselves as the energy backbone of the AI economy, while others—especially in New England and parts of the West Coast—risk being left behind. This emerging gap is what The Grid Divide defines and measures.

    At the heart of the report is the Grid Readiness Score™ (GRS), a first-of-its-kind ranking of all fifty U.S. states based on their ability to power AI-driven load growth. The GRS incorporates five critical factors:

    1. Load Tolerance – headroom to absorb new demand.
    2. Capacity Flexibility – interconnection and transmission availability.
    3. Permitting Velocity – how fast infrastructure can be approved.
    4. Resource Mix – balance of reliable and clean energy.
    5. Investment Visibility – scale of projects already announced or underway.

    The results are striking. Georgia (87), Texas (86), and Virginia (75) lead the nation. Georgia’s rise is tied to the Vogtle nuclear expansion, a streamlined permitting regime, and a flood of new hyperscale investment. Texas benefits from ERCOT’s open market, rapid transmission planning, and over 30 gigawatts of projected AI-driven load. Virginia remains the world’s largest data hub but is beginning to strain under congestion and community pushback.

    At the bottom are Hawaii (18), Rhode Island (26), and Maine (29), along with much of New England. Despite deep pools of tech talent, these states struggle with high costs, slow permitting, and limited grid capacity. California also ranks low, dragged down by permitting hurdles, escalating costs, and reliability concerns that are pushing development eastward.

    The report emphasizes that this divide is not inevitable. States can climb the rankings if they act decisively. The Grid Divide outlines a five-part playbook for lagging states:

    • Anticipate load growth with AI-specific forecasts that map demand at the county level.
    • Reform interconnection queues with transparent timelines, standardized costs, and fast-track approvals.
    • Accelerate permitting by setting statutory deadlines and pre-certifying corridors.
    • Create AI-ready zones with documented access to power, fiber, and water.
    • Rebalance resource mixes to ensure hour-by-hour reliability with firm clean energy, storage, and flexible capacity.

    The stakes could not be higher. States that deliver reliable, affordable power quickly will capture billions in capital investment, tax revenue, and job creation—not just in data centers, but in semiconductors, advanced manufacturing, and other AI-adjacent industries. States that fail will watch opportunity flow elsewhere.

    Ultimately, The Grid Divide shows that the future of AI will not be built where the coders are. It will be built where the power is. The GRS is both a scoreboard and a roadmap—revealing today’s leaders, today’s laggards, and the path forward for states willing to act.
